This cycle should be reserved for a clear day so that the Clyde views can be appreciated properlyand Ben Lomond will be visible.Parking is at the Castle Semple visitor centre and the routes starts along the cycle way from the centre but leaves it after a couple of kilometres.The early part of the route is twisty little lanes where a proper map (63) will be useful.There is a cafe in Kilmacolm for a lunch break.
